9 Claims.

This invention relates to card printing machines and the object of theinvention is to provide a machine for printing cards in which thepressure applied in the printing operation may be varied by means of aleverage controlled manually by the operator.

Another object of the invention is to provide a card printing machineincluding a printing bed and a card holding means at one end of theprinting bed, the said card holding means being releasable by theoperator when the carriage is moved to position over the card holdingmeans.

A further object of the invention is to provide a card printing machinecomprising a printing bed having a card holding means at one end and acarriage movable longitudinally of the printing bed, said carriagecarrying a pressure roller and a member adapted to be turned in onedirection to move the pressure roller into engagement with the card andadapted to be turned in the opposite direction when over the card holderto release the card holding means.

Another object of the invention is to provide an eccentrically mountedpressure roller including a pivoted supporting member having a handlewhereby the pressure on the pressure roller may be varied by varying theangular position of the handle in'moving the carriage longitudinally ofthe printing bed. I

A further object of the invention is to provide a spring actuated cardholder comprising a pivoted card holding member having an edge arrangedto engage and grip the card and the pivoted card holding member beingturnable on its pivot against the tension of the springs to allowrelease of the card.

These objects and the several novel features of the invention arehereinafter more fully described and claimed and the preferred form ofconstruction by which these objects are attained is shown in theaccompanying drawings in which- Fig. 1 is a plan view of a card printingmachine embodying my invention.

The device, as shown more particularly in Fig. 3, comprises a printingbed I which is supported on two channel side members 2 which are se-1934, Serial No. 730,790

cured to the printing bed I. A track 3 is secured to the oppositelongitudinal edges of the printing bed. A carriage bracket 4 is providedat each side of the printing bed I and these carriage brackets 4 eachcarry a series of four rollers 5, 6, l, and 8, as shown moreparticularly in Fig. 4. The rollers 5 and 8 are each flanged rollers, asshown in Figs. 3 and 4, and the flanges ride against the outer edges ofthe printing bed i and the track members 3. By this arrangement thecarriage brackets 4 may be moved longitudinally of the printing bed ineither direction. An elongated U-shaped member 9 is provided, as shownin Figs. 1, 3, 4, and 5, and each end of this U- shaped member isprovided with a pivot stud III which is rotatably mounted in thecorresponding carriage bracket 4.

A shaft l l is mounted in the ends of the U- shaped bracket 9 eccentricto the axis of the pivot studs l0 and a roller 12 is rotatably mountedon the ball bearings l3 supported on the shaft II. A handle I4 is alsosecured to the center of the U-shaped member 9 whereby the member 9 maybe turned on the studs ID which act as a pivot for the member 9. By thisarrangement, as will be understood from Fig. 4, the roller l2 may beturned from the position shown in full lines in Fig. 4 to that shown indotted lines in the said figure. The type l5 are mounted on the printingbed I, as shown in Fig. 5, or in any other suitable manner and atransverse member 16 is secured to the printing bed I by the screws IT.This member i6 is provided with lugs l8, as shown in Figs. 5 and 6, anda plate I9 is provided having depending lugs 20 extending between thelugs I8 and a pin 2| extends through the lugs l8 and 20 so that theplate 19 is pivotally mounted on the twopins 2|, shown in Figs. 5 and 6.This plate I9 is provided with a downwardly bent flange 22 at theforward edge and at the rear edge a coiled spring 23 forces the memberl9 upwardly on its pivot 2| to force the clamp jaw edge 22 downwardlytoward the top surface of the member IS. A guide 24 is secured to theplate l9 and forms a guide for the coiled spring 23. A cross member 25is provided for the carriage, as shown in Figs. 1, 4, and 5, whichextends between the two movable side carriage brackets 4 and is securedthereto by the screws 26 which extend. through the adjacent member 4 andare threaded into the ends 21 of the cross member 25. By thisarrangement, the member 25 rides with the movable carriage and a pair ofpins 28 are supported in the cross member 25 on the springs 29.

Threaded through the ends 2'! of the member 25 are a pair of adjustingscrews 30 which are engaged by the faces 3! of the U-bracket 9 when inthe position shown in full lines in Fig. 4. These screws 36 areadjustable and act as stops to limit turning movement of the member 9 onthe pivot studs H] by means of the handle l4. The screws 33 may be soadjusted that the maximum amount of pressure with which the roller l2presses downwardly on the type is accurately limited.

In operation, the carriage is moved to the position shown in Fig. 4 inwhich position the upturned end 32 of the track 3 provides a stop. Atthis time, the handle l4 may be turned from the position shown in fulllines in Fig. 4 to that shown in dotted lines. When so turned, thepivoted member 9 engages the upper ends of the two pins 28 and forcesthese pins downwardly against the tension of the springs 29. In thisposition shown in Fig. 4, the pins 28 are directly over the rear portionof the clamp member I9 and thus force the clamp member downwardlyagainst the tension of the springs 23. This raises the forward edge 22of the clamp away from the member [6 allowing a card 33 to be positionedon the type I 5 so that the edge of the card may be inserted between theclamp edge 22 and the transverse member l 6. At this time, the handle l4may be turned from the position shown indotted lines in Fig. 4 to thatshown in full lines. In this movement, the pins 28 are released toupward movement by the springs 29 and the clamp member !9 is released toturning movement on its pivot 2| by the springs 23. This causes the edge22 of the clamp member H) to grip the edge of the card between saidclamp edge and the member l6.

As the handle I4 is turned over to the position shown in full lines inFig. 4, the roller I2 is brought into contact with the upper surface ofthe card 33, at which time, the carriage is ready for movementlongitudinally of the machine. The handle M is then in the positionshown in Figs. 1, 2, and 3 and the handle may be grasped in order todraw the carriage longitudinally of the machine. In this connection itwill be noted that the more pressure exerted in pulling down on thehandle the more pressure is applied to the card 33 being printed and theamount of pressure that can be so applied may be limited byadjustment ofthe adjusting screws 30. The operator, by grasping the handle I, movesthe carriage to the right of Figs. 1 and 2 and the rollers 6 and 8 mayengage the screws 34 at the end of this stroke which form stops for thecarriage. The carriage is then pushed back by means of the handle M tothe position shown at Fig. 1, at which time, the handle may be turnedover to the position shown in Fig. 5 and in dotted lines in Fig. 4 torelease the card 33. At this time, the type may be again inked and a newcard inserted in position to be printed. I have not shown the type inFigs. 1, 2, 3, and 4 as any suitable means maybe provided for supportingthe type which maybe arranged in accordance with the design to beprinted on the card.

When the carriageis moved'longitudinally of the printing bed and theroller is pressed downwardly by pressing downwardly on the handle [14,downward pressure is applied to the rollers 6,

shown in Fig. 4, and upward pressure is applied to the rollers 1 shownin said figure.

This freesthe rollers 5 and 8 from pressure so that there is no grindingaction between the flanges of the rollers 5,and 8 and the a j mstructions and, at the same time, is limited in its downward pressure bysaid adjusting screws 33.

From the foregoing description it becomes 65* dent that the device isvery simple and eificient in operation, will not easily get out oforder, is

composed of few parts and is of consequent low manufacturing cost andprovides a device which accomplishes the objects described.
